Question

2. Walter bought a 21-pound bag of flour. He used 4.2 pounds of the flour.

He stored the rest of the flour in 2 2/5-pound portions. What is the number
of 2 2/5-pound portions he stored?

Answer 1

Hi, I did
21-4.2=16.8 left
Since he stored in 2 2/5 portions I converted 2 2/5 to 2.4 and did 16.8/2.4=7 therefore he stored the flour in 7 portions.

Hope this helps !
